Application filed August 24, 1912.V Serial No. 716,898.

To all whom it may concern Be it known that I, THOMAS H. SEELY, a, citizen of the United -States, and resident of Dorchester, county of Suffolk and State of lvlassachusetts,` have invented an Iniprovement in Work-Supports, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like Darts. Y y l -The invention to be hereinafter described relates to shoe supports, and more particuf larly to that type for sustaining ashoe during the action of a tool and'while'on'thel last.

As well known by those Askilled in the art,

shoe lasts are formedV with a` last Ypin ref` ceiving recess which isjdesigned to receive the last pin of a jack or shoe support, and

when the shoe is jacked to'elfect its steady support during thek action of a tool thereon the last is held between the last pin and an#y other element, such as a toe or 'other rest. In order to jack the shoe, relative movement is imparted to the last pin and toe or other rest, and to this end the last pin may be mounted totilt about a pivotal mounting in order to throw the toe portion of the shoe upon the toe or other rest. This tilting action of the last pin is'preferably transmittedV through a yielding element, so that the last may not be broken or injury done the shoe. The last pin sockets in lasts, however, are not always uniformly located, but vary in different lasts and even in lasts Vof the same size, not only in position but also in their inclination with reference to the top or crown of lasts, so thattilting action of the last pin that will be sufiicient to properly jack the shoe in' one case would be unsuitable in another case, and,where the jacking action is transmitted through a yielding elesuch for instance as pointed out in the patentto Plant, No. 958,283, the eective tension of the yieldingA element -willV so far vary that it may be too great in some cases and too little in others. j

ith` these general facts in mind the-aims and purposes ofthe present invention are to provide means whereby the shoe may be jacked with uniform pressure"upon'.the toe or other rest, regardless of variations in the Y position or inclination of the last pin sockets,-all as willhereinafter more fully-appear from the following description and accom'-y the jacking slide and associated parts.'V

panying drawing of one form of means for carrying the invention into practical eect, it being 'understood that in its truescope the invention Vis defined by vtheclaims,`

. In the drawings Figure 1` isaside elevation, partlyin section', of a jack or shoey support embodying a convenient and prac-- tical formy of theinvention; and F ig. 2 is a detached ydetail in' longitudinal section of l As avconvenient illustrative form of the invention, the drawings illustrate the general character -of jack or shoe support shown and Vdescribed in i the` Plant Patentv No1 958,288,"May. 17, 1910, and reference `mayl be made thereto for adetail disclosure ofl'thosev featuresof4 the jack-or shoe supportnet esf sential tothe present invention andthe gen-i eral manner of operation, it being'understood that the invention itself is not restricted thereto, but is applicableto other forms of jacks or shoe supports.

Rising fromY the main portion of the jack 1, is a post 2, and pivotally mounted at`3 on the post 2 is the lastv pinsupport 4 hav` ing the last pin 5, the lower end'of said last pin support l being connected at 6 to an upwardly projecting arm 7 risingfrom an actuating 'link or slide 8said link or slide' 8 being preferably formed as a yielding member, and as shown in the present forni' of the invention comprisin'gwtwo parts 9 and 10, connected-by an adjusting bolt or` rod 11, in aYV manner that will presently ap` pear, the construction being such that'upony movement of the link orfY slide 8 tothe left,

crank arm 14 connected by a link 15 to` an eccentric shaft 16, forzoperating the, jack lock,rall substantially a'sfully Ydescribed yin Vthe said Plant patent, to vwhich reference@ may be had, but as these lockingdetails form noessential part ofthe present' inveni tion and may be as set forth by said patentv A Y or otherwise, the particulars thereof are not here shownf W y The toe rest 17 is preferably mounted for' adjustment on the carrier 18 secured to a.l toe restsupport 19 pivotally mounted upon the jack at'QO, andtheseparts and their operative' relation may be the same as,k fully described in the said Plant patent, or of any rio desired armati, the 'essential' in this respect being that the jack be provided with some kind of a toe rest or other support to receive and'sustainthe toe portion ofthe shoe when the latter is jacked.

As hereinbefore stated, the link or 'jack-r collar- 2lgand the` part l0 ofk the slide is a spring 25,' normally holdingathe partsV 9 and '10 of the slide iny separated relation, and j.

the adjusting` sleeve 2l is provided with a capstan head 26jvhereby it may be rotated foradjusting the twofparts of the slide relatively toeach other, the constructionV being-V Y u such thatlby rotation ofthe .adjusting sleeve jacke l v While the particular devices herein shownand described present a practical and con# venient. form -ofgthef invention and enable 2l between ythe nuts and collarQl, the:l two parts 9 and 10 of' the slide may be adjusted.

toward or from each other to thereby vary the length ot the slide without at the same time varying or( disturbing the jacking tenfA 3.0i

sion of the jacking springQ, and conversely by proper manipulationpf the .nuts 23pA and the adjusting sleeve Qlfthe jacking tension ofthe jacking s pring'Qmay be variedv to suit conditions of use without'varying the length of the jackingl slide.`

The arm 7 connected to the last pin support ,l is secured to or formed as part of the part 9, of' the jacking slide,V consequently variation in the lengthof the jacking slide by manipulation of theadjusting sleeve 21 will vary the initial inclined position of the last pin 5to suit the varying inclination of last pin sockets in different lasts without at the same timedisturbing the jacking tension of the jackingspring-with the result .that re-y gardless of such variation sockets of different lasts, shoes maybe secured.

Rising from the lpart l0 of the jacking slide 8 isa lug or projection 27 having a in the last .pin uniform acking of yslot 28 whichl is engaged by apin or projection 29 carried by the jacking lever 13 wherebyupon movement vofthe jacking lever contra-clockwise, Fig. l, movement will be imparted to the acking slide and through the spring 25 the shoes tobeuniformly and yieldingly jacked regardless ofthediferent positions or inclinations ofthe last pin sockets in different lasts, itis tov'be understood that the invention lst-subject touinodilication Vin .details and part'91is an adjusting.
